I18N::Collate - compare 8-bit scalar data according to the current locale
WARNING: starting from the Perl version 5.003_06 the I18N::Collate interface for comparing 8-bit scalar data according to the current locale
HAS BEEN DEPRECATED
That is, please do not use it anymore for any new applications and please migrate the old applications away from it because its functionality was integrated into the Perl core language in the release 5.003_06.
See the perllocale manual page for further information.
use I18N::Collate; setlocale(LC_COLLATE, 'locale-of-your-choice'); $s1 = new I18N::Collate "scalar_data_1"; $s2 = new I18N::Collate "scalar_data_2";
This module provides you with objects that will collate according to your national character set, provided that the
setlocale() function is supported on your system.
You can compare
$s2 above with
$s1 le $s2
to extract the data itself, you'll need a dereference:
This module uses POSIX::setlocale(). The basic collation conversion is done by
strxfrm() which terminates at
NUL characters being a decent
collate_xfrm() handles embedded
NUL characters gracefully.
The available locales depend on your operating system; try whether
locale -a shows them or man pages for ``locale'' or ``nlsinfo'' or the direct
ls /usr/lib/nls/loc or
ls /usr/lib/nls or
ls /usr/lib/locale. Not all the locales that your vendor supports are necessarily installed:
please consult your operating system's documentation and possibly your
local system administration. The locale names are probably something like
xx_XX.(ISO)?8859N, for example
fr_CH.ISO8859-1 is the Swiss
(CH) variant of French (fr),
ISO Latin (8859) 1 (-1) which is the Western European character set.
